DOI: 10.1007/s00709-020-01541-w
Abstract: The term “cytoskeleton” has been coined, when, from the early 1960s, electron microscopy has revealed filamentous structures that seemed to organise the cytoplasm (“microtubules”, Ledbetter and Porter 1963; “microfilaments”, Kamiya and Kuroda 1966). Onlywith the… read more here.

DOI: 10.1016/j.cub.2021.08.068
Abstract: Vertebrate craniofacial morphogenesis is a highly orchestrated process that is directed by evolutionarily conserved developmental pathways.1,2 Within species, canalized development typically produces modest morphological variation. However, as a result of millennia of artificial selection, the… read more here.

DOI: 10.1016/j.fishres.2019.105375
Abstract: Abstract The beak of cephalopods (in particular octopods, where statoliths are not suitable) is a useful tool for age estimation and the aging method provides essential information on cephalopod growth and life cycles. These parameters… read more here.

DOI: 10.1111/1365-2435.12890
Abstract: Summary The diversity of beak shapes among birds is often assumed to be largely the result of adaptations to different feeding behaviors and diets. However, this assumption has only been tested for a small subset… read more here.
